(Cl. l-145) 3 Claims.

This invention pertains to advertising sign containers for attachment to parking meter posts, or standards.

Heretofore, several devices have been tried which were thought suitable for holding signs on parking meter posts, however, in each case, the device was found defective. From observation and experiment I have developed the device hereinafter illustrated and described, which overcomes dilculties heretofore encountered and at the same time complies with the legal and safety requirements for such a device.

One of the objects of my device is to provide a case which can be securely mounted on a parking meter post and which will hold signs or advertising matter in a manner to be clearly visible to passers by, and which will protect such matter from the Weather and from undesired removal or tampering.

Another object is to provide a case of transparent material having flat sides behind which signs or advertising matter can be inserted and held in position together with means for attachment to parking meter supports, and with admission to the interior made diicult to any but authorized persons.

A further object is to provide a sign containing case made of transparent plastic, with means for fastening to a vertical tubular member, such as a parking meter post, to render it weather and tamper proof.

Other objects will appear hereinafter.

I attain. the foregoing objects by means of the devices illustrated in the accompanying drawings in which- Figure 1 is a perspective view of the container in use.

Figure 2, a transverse mid-sectional elevation of the case drawn on an enlarged scale, and

Figure 4, a horizontal section taken substantially on line il- 4, Figure 2.

Similar numerals refer to similar parts in the several views.

The container body 2 is a hollow case preferably molded of one of the well-known transparent plastics. It has a general rectangular section in all three dimensions. A, hole 4 is provided in the top 5 for admission of the cylindrical standard 6, which in this case is a tubular parking meter post. The front and rear faces 'I and 8 constitute viewing windows through which signs IIJ printed on cardboard may be easily observed. These cardboard signs are held in place by grooves I2 extending along the inner edges of the inner faces of the viewing windows. Around hole I in top 5 there is an inwardly extending annular collar Ill sized to accept standard 6 with a sliding fit. Nuts I'I are set intorecesses in the inner face of this collar to receive set screws I8.

A bottom plate 2E! fits within the opening 26 lin the case bottom. It is provided with an opening 2l sized to receive standard G, and an upwardly extending collar 22 formed around this opening drilled and threaded radially to receive a small hollow head set screw 23 which can be reached with an Allen wrench inserted through a hole 24 in case face 8. The outer edges of this bottom plate iit into a rabbet 25 formed around the edges of bottom opening 26 of the case body 2.

In use the bottom plate 2E! is first placed on standard 6 and dropped below the level at which it is to be later attached. Case 2 is then positioned on the standard and nuts I8 tightened to secure it in the position desired. This is best done with a ratchet box wrench. Cards I0 are then inserted, and lastly bottom plate brought up, iitted into opening 2li, and fixed in place by tightening screw 23.

All this is done to position the device at a desired position on the standard below the parking meter 30, as shown in Figure l. Obviously, the meter is removed when the case parts are slipped over the standard After the case is placed in position, the meter is replaced and the completed installation is accomplished.

Thereafter sign cards Il) may be replaced whenever desired by merely loosening screw 23 and sliding bottom plate 20 down so that it is out of the way. After sign cards are replaced the bottom plate is again secured in position to close the case body.

Whereas I have illustrated but one form of my sign container, it is conceivable that many variations can be made in the structure shown.

Likewise changes and substitutions of parts can be made, all of which, however, may well remain within the spirit and intendrnents of the invention. Therefore, I wish to be limited only by the following claims.

I claim:

1. An advertising sign container for attachment to parking meter posts comprising, in combination, a hollow case having transparent viewing windows, an opening at the top of said case provided with an inwardly extending Collar, radially engaging set screws operative in said collar, an opening in the bottom of said case, a removable bottom plate adapted to fit into and close said opening having an upwardly extending collar provided with a set screw, said case being provided with an opening to permit access to said set screw when said plate is in closed position.

2. A sign container for use on parking meter standards comprising, a rectangular case of transparent plastic material having parallel flat side faces constituting Viewing windows, means for retaining sign-bearing cards behind said windows, including grooves formed adjacent the side edges thereof, an opening to receive a parking meter standard formed in the top of said case, a collar extending inwardly from said opening provided with radially operative set screws adapted to engage said standard, an opening in the bottom of said case to allow access to said sign cards, a bottom plate adapted to t into and close said bottom opening, having a hole sized to receive said standard and an upturned collar surrounding said hole, a set screw operative in said collar'to engage said standard, and an access hole drilled in said case to admit a wrench to operate said bottom plate set screw when in closed position.

3. A sign container for attachment to parking meter standards, including in combination, a rectangular case of transparent material having two at Vertical sides constituting viewing windows, grooves formed along the inner side edges of these windows adapted to retain cards in position adjacent said windows, an inwardly collared opening in the top of said case, set screws operative in the collar of said collared opening, adapted to engage a standard inserted through said opening, a rectangular opening formed in the bottom of said case to provide access to sign cards held in said grooves, a rabbet groove formed along the edges of said opening to receive and secure a bottom plate, together with a bottom plate tted into said bottom opening having a central collared opening to receive a sai-d standard, a set screw operative in the collar of said collared opening in said plate, adapted to engage said standard, an access opening in said case body adjacent said set screw, and cards bearing written matter fitted into said grooves adjacent said viewing windows.
